Description:

WARNING: This product is for research use only, not for human or veterinary use.

QNN03771, also known as Co(II) meso-Tetra (4-methoxyphenyl) Porphine (1-3% chlorin) is a synthetic porphyrin derivative which has been used as a potentiometric sensor and is an effective catalyst of dibenzothiophene. Cobalt(II) porphyrins are strong catalysts of selective cyclopropanation for alkenes with ethyl diazoacetate. This product has no formal name at the moment. For the convenience of communication, a temporal code name was therefore proposed according to MedKoo Chemical Nomenclature (see web page: https://www.medkoo.com/page/naming)
